The active-low, push-pull output asserts reset when the monitored supply drops below that threshold and holds it for a minimum of 120ms after the rail recovers. This part is typically specified by hardware engineers who need a clean, deterministic reset pulse for a 3.3V or 3.0V microcontroller, FPGA, or SoC without extra features like watchdog or manual reset. ## Industrial temp and SOT-23-3 footprint ## Active production — sourcing against the BOM line It is ROHS3 compliant.","metaTitle":"TPS3809L30DBVT Supervisor IC – Active Low Reset","metaDescription":"Texas Instruments TPS3809L30DBVT simple reset/power-on reset IC.
